    An old form is throwing a 404 error with a CSS file

    Asked by sobrien on March 10, 2017 at 12:22 PM


    We have a form that seems to have an old attached style sheet from a non-existent theme attached that throws a 404. We are a library and have kiosk browsers for our catalog only computers. Because of this 404 error the web page does not load on these kiosks: https://www.dcl.org/adult-education The form in question is under "Tech Tutoring". https://form.jotform.us/52096044569158

    I would like to just detached the CSS file: https://cdn.jotfor.ms/themes/CSS/54945ae9700cc494668b4567.css? How do I do that? Am I going to have to rebuild the form? I'd hate to have to do that.

    Thanks for your help,

    Hello Dale, you're correct. This CSS file https://cdn.jotfor.ms/themes/CSS/54945ae9700cc494668b4567.css renders a "theme not found" error when viewed directly from the browser.

    Looks like it happens even in the stand-alone version of your form https://form.jotform.com/52096044569158

    My question would be, does the appearance of the form look different from how you're expecting it to be? Or you're just concerned about the 404 error thrown on the console logs?

    If the look and feel is different because of this error, do you have a screenshot of how it's supposed to look like?

    If it's relatively the same, and all you wanted is to get rid of the 404 error, you can try the following:

    1. Copy the custom CSS Codes you currently have on your form. Here they are:

    .form-all {




    .form-line {

    margin: 0;

    padding: 10px 0;


    .form-label-top, .form-label-left, .form-label-right {

    font-weight: normal;


    2. Set the form's theme back to the Default Theme. This would essentially trigger the builder to load the newest CSS files.

    3. After setting the form's theme back to default, re-paste the CSS Codes you copied to preserve the original layout of your form.

    All 3 steps are shown on this cloned copy of your form:
